Brief Summary

RATIONALE: Drugs used in chemotherapy, such as capecitabine, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving capecitabine and oxaliplatin together with bevacizumab may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving oxaliplatin and capecitabine together with bevacizumab works in treating patients with metastatic or recurrent colorectal cancer.

Detailed Description

OBJECTIVES:

Primary

* Evaluate the response rate in patients with previously untreated metastatic colorectal cancer treated with capecitabine, oxaliplatin, and bevacizumab.

Secondary

* Assess time to progression (TTP), disease-free survival (DFS), and overall survival (OS) in patients treated with this regimen.

* Assess the safety and tolerability of bevacizumab, oxaliplatin, and capecitabine in patients with previously untreated metastatic colorectal cancer.

Exploratory

* Evaluate the effect of this regimen on the biomarkers of angiogenesis.

* Assess the effect of this regimen on wound angiogenesis.

OUTLINE: Patients receive oral capecitabine twice daily on days 1-5 and 8-12, oxaliplatin IV over 2 hours on day 1, and bevacizumab IV over 1-1½ hours on day 1. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study.

Primary Outcome Measures
NameTimeMethod
Response Rate (Percentage of Participants With Partial or Complete Response)After all subjects were evaluated for restaging which occured every 9 weeks from drug initiation until disease progression, assesed up to 24 months.

Restaging scans occurred every 9 weeks from time of study drug initiation until disease progression.

Disease assessment was performed and recorded according to the Response Evaluation Criteria in Solid Tumors (RECIST v.1.0) Guidelines.

The definitions were:

Complete response (CR)- Disappearance of all target lesions Partial response (PD)- At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD Stable disease (SD)- Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started Progressive disease (PD) - At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions

Secondary Outcome Measures
NameTimeMethod
Disease Free SurvivalFrom time of treatment until documented progression or death from any cause, whichever came first, assesed up to 60 months.

Disease assessment was performed and recorded according to the Response Evaluation Criteria in Solid Tumors (RECIST v.1.0) Guidelines.

Progressive disease is defined as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

Time to ProgressionFrom time of treatment until documented progression, assesed up to 60 months.

Disease assessment was performed and recorded according to the Response Evaluation Criteria in Solid Tumors (RECIST v.1.0) Guidelines.

Progressive disease is defined as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

Overall SurvivalFrom time of treatment until death from any cause, assesed up to 60 months.

Average months of survival of participants after receiving study drug.

Safety and TolerabilityAfter all participants went off study drug regimine.
